anyhow, if you have the money, get it then, it's ur choice.
but for all practicality, it's not worth whatever cooling advantage it might bring. I've read reviews after reviews about how it doesn't cool more than 1-5c even in the best conditions. That's not much, considering the price, or what you can do with just a couple more fans.
Lightweight is one DEFINITE advantage, but that's about it....if you lug it around all day.
Also it's cool to look at...for the first month I guess. and there were a couple of reviews about how easily it gets scratched. not so pretty then.
The ones here that dont own a aluminum case, including me, have done researches about it, and that's why we've decided against it.
